There are three main types of hearing protection that people can wear to help reduce the impact of noisy environment and risk of developing noise-induced hearing loss. These include earplugs, earmuffs and semi-insert earplugs.
What are the four basic types of hearing protection?
What types of hearing protectors are available?Ear plugs are inserted in the ear canal. … Semi-insert ear plugs which consist of two ear plugs held over the ends of the ear canal by a rigid headband.Ear muffs consist of sound-attenuating material and soft ear cushions that fit around the ear and hard outer cups.

External white noise machines can be used in addition to earplugs to completely muffle other sounds. They can also be used instead of earplugs. Other devices are also available that you can wear for noise reduction during sleep, including earmuffs.
What is a safe hearing level?
Decibel Level Sounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time. Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher are at a much greater risk for hearing loss.
How do I choose hearing protection?
Three Tips for Choosing the Right Hearing Protector1) Know How Much Noise Reduction You Need.

Which is better ear plugs or earmuffs?
Because they fit directly into the ear canal, ear plugs offer greater protection than ear muffs. This means that ear plugs are suitable when you need the highest levels of protection, for instance in very loud workplaces such as factories, airports, and foundries.

What does NRR 33 mean?
Noise Reduction RatingA Noise Reduction Rating or NRR is a system used to measure the amount a hearing protection device is capable of reducing sound exposure in decibels. … So if a hearing protector has a rating of 33 NRR, you would do (33 – 7) / 2. This comes out to be 13. So in actuality, only 13 decibels are being reduced.
What is the minimum lighting required by OSHA?
